This reduces point cache sizes dramatically especially if particle
life time is small compared to total simulation length. For example
with the settings: particle amount = 10000, start = 1, end = 200,
life = 10, cache step = 1, the unoptimized blend file size (compressed)
was a little over 22 Mb and with this optimization the file is a little
under 2 Mb (again compressed). In addition to saving memory/disk space
this also probably speeds up reading from cache, since there's less
data to read.
As an additional fix the memory cache size (displayed in cache panel)
is now calculated correctly.
Modifier code was asking for filtered textures without sending derivatives.
Disabled this and also checks for filtered/non-filtered.
Brecht, I assumed this was ok due to the existence of the p->osatex variable
- if this isn't what you had in mind, please change or let me know :)
unrelated changes that ended up being more trouble to commit separate...
- removed BLI_split_dirfile(), was nasty, occasionaly modifying the source string, it could create directories and used the $CWD in some cases. was only used in 2 places in filesel.c, if this gives problems can address without bringing back this function.
renamed BLI_split_dirfile_basic --> BLI_split_dirfile
- view3d_operator_needs_opengl was being called for offscreen render when it wasnt needed.
there is sufsurf modifier first in the stack.
Some optimizations in curve_calc_modifiers_post():
- Calculate allverts array only for curve modifier applying to curve
without derived mesh.
- Do not calculate deformedVerts array each time deformation modifier
is applying to derived mesh.
* I put it under General->System. Not sure is the better place for it though (space_userpref.py)
** also: creator.c fix to avoid autoplay of games when scripts are disabled.
- use render mesh settings rather then view settings.
- fixed bug with brush size being overwritten and allowing non mesh objects to be projected onto.
- made the paint loop less messy & minor cleanup
Used approach with creating DerivedMesh for curves whet they've got such modifiers.
Available modifiers are: array, edge split, mirror, solidify, subsurf.
Animation conversion needed to make transform channel driver vars (for bones) to be in local space, since that's what the old code did (albeit in a slightly more roundabout way).
Transform channel drivers for bones in 'localspace' was using the wrong matrix when getting the transforms. I had been assuming that pchan->chan_mat always contained only the matrix-ised transform values stored in the pchan (which is true while constraints are being evaluated, but not afterwards).
Changes:
- Added a new function to calculate this matrix instead of directly writing it on the pchan->chan_matrix field.
- Also, made the normalisation of the quaternion values during this process be done on a temp var instead of on the stored value. This was a constant source of confusion in the past, so let's see if we can do without it now :)
Unrelated to this commit, I've also fixed a compiler warning with previous commit that I missed (missing include).
- disable running scripts automatically
- set sequencer image preview
- added a 3D viewport in the python script screen & selected 'Text' in the next editor.
- enable stamp rendertime by default. (stamp its self is disabled)
- set the stamp font size to 12 (was 8, too small)
also set the default font size to 12 for new scenes.
His log:
There is a small typo in copy_curve(): there will be serious troubles
if this functions is called for OB_FONT in edit mode (for my cases
it is segmentation fault).
I think we should set editfont to NULL for cloned curves (as it is made
for edit nurb).
This bug was found by trying to edit text with applied Cast modifier
and while I was searching what's wrong, I've found that in
castModifier_deformVerts() DerivedMesh is creating for all objects,
but in castModifier_*_do() derived mesh is used only for OB_MESH
objects. Maybe this place could be optimized a bit by skipping DM
creation for non-meshes?
rename BKE_get_image_export_path() to BKE_rebase_path() and take a filename arg rather then an image.
obj export file copy was also not working because of a missing import.
* Effectors now work with hair dynamics.
* Hair dynamics has a new "Collider Friction" parameter that works similarly to internal friction except now all collision objects effect the hair velocity. Useful for quick'n'dirty interaction with objects as the calculations are really fast, but doesn't really take away the need for proper hair-object collisions.
* The exact location of particle birth wasn't cached if cache step was greater than 1, so the interpolation from an unborn particle to a living one wasn't accurate at all.
* Although not ideal, the current solution is to copy the birth location to the previous cached frame so it's always exact. This should work properly for memory & disk cache.
* This fix shouldn't cause any problems, but exhaustive tests of caching are difficult so be sure to let me know if there's strange behavior.
